Four heterotrinuclear strings of metal atoms stabilized by dipyridylamide (dpa-) ligands were synthesized and characterized. The metal frameworks of Ru2Cu(dpa)4Cl2 (1), its monooxidized counterpart [Ru2Cu(dpa)4Cl 2]PF6 (2), and their nickel homologues, Ru 2Ni(dpa)4Cl2 (3) and [Ru2Ni(dpa) 4Cl2]-PF6 (4), were shown by X-ray diffraction to be nonsymmetric, in spite of a severe disorder affecting the metal positions. The metal string is composed of a Ru dimer with a short Ru-Ru bond that is completed with the heterometal at a longer distance from the central ruthenium atom. This nonsymmetric structure was confirmed from NMR spectroscopy. The [Ru2M]6+ framework of 1 and 3 was shown from spectroelectrochemical analysis and DFT calculations to exist in the form of a mixed-valent [Ru2]5+ moiety coupled to a formally M + heterometal. The temperature-dependant magnetic susceptibility of these compounds is reported and interpreted by means of a model previously applied to [Ru2]5+ complexes. The redox chemistry of 1 and 3 was investigated by cyclic voltammetry, and the electronic structure of the mono- and dioxidized species was assigned from the observed changes in the UV/Vis spectra and from DFT calculations.

The crystal structures of complexes [Mn(tolf-O)(tolf-O,O?)(phen)(H2O)], [Mn2(mu 2-tolf-O,O?)2(tolf-O,O?)2(bipyam) 2], [Mn2(mu2-H2O) (mu2-tolf-O,O?)2(tolf-O)2(py) 4]·1.5MeOH·py, and [Mn(mu2-tolf-O, O?)2(DMF)2]n have been determined by X-ray crystallography. The interaction of the complexes with serum albumin proteins was investigated, and relative high binding constant values were calculated. The ability of the compounds to scavenge 1,1-diphenyl- picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid), and hydroxyl radicals was evaluated, and [Mn(tolf)2(phen)(H 2O)] was the most active scavenger among the compounds. The compounds have also exhibited noteworthy in vitro inhibitory activity against soybean lipoxygenase. UV titration studies of the interaction of the complexes with calf-thymus (CT) DNA have proved the binding to CT DNA with [Mn(mu 2-tolf)2(DMF)2]n exhibiting the highest DNA-binding constant (Kb = 5.21 (±0.35) × 105 M-1). The complexes bind to CT DNA probably via intercalation as suggested by DNA-viscosity measurements and competitive studies with ethidium bromide (EB), which revealed the ability of the complexes to displace the DNA-bound EB.

Optimisation of a high-throughput screening hit resulted in the discovery of 4-(substituted amino)-1-alkyl-pyrazolo[3,4-b]pyridine-5-carboxamides as potent and selective inhibitors of Phosphodiesterase 4 (PDE4). Herein, we describe early SAR studies around this novel template highlighting preferred substituents and rationalization of SAR through X-ray crystal structures of analogues bound to the PDE4 active site.

HPLC of Formula: C14H20O10, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature 10343-06-3, C14H20O10. A document type is Article, introducing its new discovery.

In the present study, Lactobacillus plantarum glycolipid (GL1) molecule in beta-configuration and its fatty acid analogues were synthesized using trichloroacetimidate methodology. The beta-configuration of the GL1 molecule was unambiguously assigned by NMR studies using 2D-ROESY (NOE) and J-coupling analysis. Dihydrosterculic acid was synthesized using Furukawa’s reagent and the selective esterification of dihydrosterculic acid at C-3 position of glycerol was achieved with EDC-HCl at 0 C. In vitro cytotoxicity of the GL1 molecule and its fatty acid analogues was evaluated against DU145, A549, SKOV3 and MCF7 cell lines. Among all the synthesized molecules, the GL1 molecule and compound 7d showed moderate activity, while the compound 7b showed promising activity against all the tested cell lines with IC50 values of 20.1, 18.2, 19.1 and 17.6 I1/4M, respectively. In addition, all tested compounds showed poor cytotoxicity against normal HUVEC cells. The MCF7 cells when treated with compound 7b showed lower bromodeoxyuridine incorporation levels as compared to untreated cells, suggesting that the compound 7b was highly effective and inhibited the cell proliferation. In addition, the compounds showed significant increase in caspases 3 and 9 levels by inducing apoptosis in MCF 7 cells.
